Application '.iled April 3, 1912. Serial No. 688,218.

This invention relates to improvements in detachable rims, and the combination therewith of wheels adapted to receive said rims, as will be hereinafter more fully described. According to `this invention, a complete and undivided rim is provided with a contractible supporting plate fixed to the base portion ot' the rim at an angle thereto` and according to this invention the supporting plate is fixed to the said rim throughout its circumference, and has saw cuts formed-at suitable. intervals apart to give it the required fiexibility; its edge is preferably rounded to form a beading, within which is placed a rod adapted positively to expand orcontract the free edge of the supporting plate, and so cause the bead to seat itself upon or be removed from a seating carried by the wheel telly.

This construction is particularly applicable to' twin tires, as the edges ot the supporting plates alone rest upon the wheel telly, the rims overhanging both sides of the same; it will be seen that the felly will not require to be cut away for the purpose of allowing the passage of the valves of pneumatic tires.

The invention also comprises a wheel having a vplurality of rims each composed of a complete and undivided detachable rim, and

each provided with a supporting plate capa-` ble of contracting and expandmg.

Reference is had to the -accompanying drawings, in which the same parts are indicated by the saine letters throughout the several views.

Figure 1 is a :trontelevatiom showing the detachable supporting plate and rim carried thereby detached from the wheel, and Without the tire. Fig. 2 shows a cross-section along the line 2-2 of Fig. l, and looking in the direction of the arrows. Fig. 3 shows a section through the telly of the wheel and the detachable rim and tire, the section plate In assembling the parts, the

through the detachable rim being shown along the line 3-3 of Fig., l, the ligure being especially designed to show a means for locking the rim against circumferential motion. Fig. 4 shows a section along the line i--i otI Fig. 3, and looking in the direction of the arrows. Fig. 5 shows a crosssection through a felly and telly band, showing the demountable rims used with twin tires. Fig. 6 shows a lsection along the line -6 ot Fig. 5, and looking in the direction f the arrows, and Fig. 7 shows a modification in which the demountable rim is adapted to be attached to the rim already onv the Wheel, for use in cases of emergency.

Referring to Figs. 1 to 6, a is a continuous, undivided rim of t e ordinary clencber.

tire, and b is a support'ng plate secured to the rim in any convenient way, and having one edge bent over andlturned up, as at b, the bent over edge forming a bead c, in which the rod d, bent to form a split ring, is inclosed. The upturned edge b ot the supporting plate b serves to engage the inner face ofthe rim a, to limit the expansion. This plate b is provided with a series of cuts from the interior part of the way through, as at z', (see Fig. l) to permit expansion and contraction of the same, and of the ring d; and this expansion and contraction is effected in any convenient way, as by means of the right and left-hand screw L; shown in Figs. l and 2. f is a wooden felly, attached to the spokes (not shown), and g is a steel hoop or elly band permanently attached to the telly, as is well known in the art. In the form of device shown in Figs. 2 and 3, thispermanent band g is provided at one edge with an outwardly projecting flange y', to engage beneath the rim a, and at the otherl edge with a grooved channel, adapted to receive the bead c of the art b4 and ring al are distended by means o the right and left-hand screw h, the bead c is slipped over the groove g2, 'and the parts are contracted by turning the right and left- `hand screw in the reverse direction.' As aresult, the bead c is held firmly in the grooved channel g2. "To prevent the rim from circumferential motion on the felly band g, any suitable locking arrangement may be provided, such as the key 7c, shown in Figs. 3 and 4 engaging in a recess in the `member b.

In the torm ot device shown .in Figs. 5

grooves g, toI receive the bead c, and the 'vertical axes ot the tires and rims are at opposite sides et, and clear ot, the telly,

l whereby the valve stem (not shown) is clear otv the telly, and there is no necessity ot pertorating the telly to receive said valve stem.

l In'v order t prevent circumferential motion,

or creeping around the wheel, the bead and the telly bandl may be 'mutually cut away,

, and caused to interlock, as shown in Fig. 6,

` and rprovided with cuts therein, the said in which g5 represents a rib separating the two grooves g4, cut into the telly band g3, and in which the bead o is cut away, as at c5', to receive said lrib g5.

In the torm ot device shown in Fig-7, the' contractile supporting plate b2 is bent, as at bo to receive the bent steel rod d, whose contrac'tionoiz" expansion contracts or expands the. tree edge b3 ot the plate b2, which tree edge is provided with an annular hook, adapted to engage the rim e, shown in dotted lines, mounteld on the telly f, also shown in dotted lines. Mounted exterior to the rod d, is a bracket plate-0'; secured to the plate b2. yThe arrangement shown in Fig. 7 is especially` intended tor use in emergencies, where, the tire on the wheel becoming defiated, it is desired, without removing said tire, to apply an auxiliary tire. The torm otgdemountable rim shownin Fig. 7 is ap'- plied to, or removed trom, the wheel in a ,n manner similar to that already described withv reference to Fig. 1. j Y

It will be obvious that various modifications might be made in the herein described apparatus, and in the combinations and arrangement ot parts which could be used without departmg trom the spirit ot my invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent ot'the United States is 1. The combination with a continuous rim, ot a supporting ,plate secured thereto plate being bent, to torm a bead, a bent rod mounted in said bead, and means tor expanding and contracting said rod and bead, substantially as described.

2. The combination with a continuous rim, ot a-supporting plate secured thereto and provided with cuts t-herein,I the said plate being bent to form a bead, a bent rod mounted in said bead,.and a right and lett contracted `mounted in said bead, and means tor ex'- panding and contracting said rod and bead, and a telly band provided with an annular groove therein adapted to engage said bead, substantially as described. `l

4. The combination withl a continuous rim. ot a supporting plate secured thereto and provided with cuts therein, the said plate being bent to torm a bead, a bent rod mounted in said bead, and a right and lett hand screw tor expanding and contracting said rod and bead, and a telly band provided with an annular groove therein adapted to engage said bead, substantially as described.

5. The combination with a continuous rim, ot a laterally projecting supporting plate secured thereto and provided with cuts therein, the said plate being bent to torm a laterally projecting bead, a bent rod mounted in said bead, means tor expanding and contracting said rod and bead, and a telly band provided with an annular groove therein` adapted to engage said bead when-in the position, substantially as described.

6. The combination with a telly band, ot a pair 4ot continuous rims, laterally projecting supporting plates secured t'o said rims, the laterally projecting edge ot each plate being bent to form a` bead, vand being provided with cuts therein, bent rods mounted in said beads, and means tor expanding and contracting said rods and beads, with a telly band provided with grooves therein,

Aadapted to engage said beads, substantially as described.

7. The combination with a telly band, ot

`a pair ot continuous rims, laterally projecting supporting plates secured to said rims, the laterally projecting edge ot each plate being bent to torm abead,vand being provided With cuts therein, bent rods mounted in said beads, and a rightand-lett hand -screw tor expanding and contracting said rods and'beads, with a telly band provided with grooves therein adapted to engage said beads, substantially as described.

In testimony Whereot, I atix my signature,in presence ot two witnesses.
